(Common Name:0Cr21Al4

 

 

Fe-Cr-Al alloy

FCHW-2, also named 0Cr21Al4, is one kind of material Fe-Cr-Al alloy.

Fe-Cr-Al alloy has the characteristic of high resistivity,low temperature resistance coefficient,high operating temperature,good anti-oxidation and anti-corrosion under high temperature.

It is widely used in industrial furnace, household appliances, industry furnace, metallurgy, machinery, aircraft, automotive, military and other industries producing heating elements and resistance elements.

FeCrAl alloy series: OCr15Al5,1Cr13Al4, 0Cr21Al4, 0Cr21Al6, 0Cr25Al5, 0Cr21Al6Nb,0Cr27Al7Mo2, and etc

Size dimension range:

Wire: 0.01-10mm

Ribbons: Thickness: 0.04mm-0.75mm, Width: 0.08mm-6.0mm
